The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a circuit card assembly, identified by NSN 0R-5998-016932359-P8 and reference number 1194935-2. The item is critical for flight operations, and due to its unstable design and marginal performance, significant changes are anticipated, which may render the current configuration obsolete. Interested vendors must be approved sources and are required to submit detailed technical data and source approval information with their proposals, as the government intends to negotiate with only one source under FAR 6.302-1. Proposals must be submitted within 45 days of the notice, and interested parties can contact Patrick Horan at (215) 697-0275 or via email at PATRICK.J.HORAN1@NAVY.MIL for further details.
